How it moves
Hockey-stick turn (asymmetric core). Dotted is skid, then the turn, then the roll into the pocket. Estimated from the coverstock, finish, core, and differential for a right-handed bowler with medium revs on a house shot. Lane conditions, speed, and layout move all of this.
How much the ball wants to hook, 1 (straight, a spare ball) to 10 (the strongest oil-eaters). The maker publishes no number for this ball, so this is estimated from the coverstock, core, finish, and differential.

4000 Abralon. Skims the oil and saves its energy for the dry part of the lane: longer skid, later and sharper hook. Polished and pearl balls. Surface changes over games, and a pro shop can take any ball either way with a pad.
